Application filed July 19, 1905. Serial No. 270,343.

To aZZ whmn it may concern.-

- Be it known that I, BENJAMIN F. FOWLER, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Lamp-Burner, of which the following is a specification.

This invention relates more particularly to means for securing better combustion and a better flame in an oil-lamp.

One of the principal objects is to provide a simple and inexpensive device of the above character and of a novel nature which will act as a deflector to direct the draft of air into more intimate relation to the flame, so as to secure better combustion, and consequently better light, said device not interfering with the radiation of the light, and, moreover, being of a nature that will permit its application to any ordinary lamp.

The referred but not the only embodiment of the invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of an ordinary lamp-burner and chimney with the improved deflector in place. Fig. 2 is a vertical sectional view therethrough on the line 2 2 of Fig. 1. Fig. 3 is a bottom plan view of the deflector. Fig. 4 is a horizontal sectional view through the lower portion thereof. Fig. 5 is a detail sectional view illustrating the frictional engagement of one of the arms with the chimney.

Similar reference-numerals designate corresponding parts in all the figures of the drawmgs.

In the embodiment illustrated the burner is of the usual type, having a threaded boss 5, an outstanding flange 6, a burner-cone 7, and upstanding yielding chimney-retaining fingers 8. A portion of a chimney 9 of the ordinary shape is shown in position on the flange 6 and is held in place by the fingers 8.

For the purpose of directing the air into more intimate relation with the flame of the burner a deflector is employed that is in the form of a cone-body 10, preferably of glass or other suitable transparent material, which body is provided with a flame-opening 11 through its top. An annular outstanding rib 12 is formed upon the lower portion of the cone-body 10, and beneath said rib are formed seats 13. These seats receive the upper ends of depending divergently-disposed arms 14, extending below the lower edges of the cone-body, said arms being preferably reversely curved, as illustrated in Figs. 1 and 2, and their lower ends being arranged to frictionally engage the inner side of the lower end of the chimney 9. The arms are held in place in their seats and upon the conebody by means of a suitable ring 15, that surrounds said body beneath the rib 12, and thus covers the seats 13. In applying this device to an ordinary lamp the deflector is placed upon a table or other flat support with the lower ends of the arms resting thereon, and the chimney is pushed down over the same, whereupon the arms will frictionally engage the inner sides of the chimney, and thus properly position the cone-body in the chimney. Said chimneyis then placed upon the lamp in the ordinary manner, with'the flame-opening 11 of the deflector-cone alined with the flameopening of the burnercone. In order that this may be more readily accomplished, the spring-arms 14 are so related to the burneropening 11 that when said arms are alined with the chimney-retaining fingers 8 of the burner the two flame-openings will be properly positioned with respect to each other.

By reference to Fig. 2 it will be clear that the air has free passage between the two cones and is directed by the deflector into intimate contact with the cone, thus securing better combustion, and consequently a better light. The deflector at the same time does not materially interfere with the free radiation of the light, as it is made of glass or other material which does not obstruct to any considerable degree the passage thereof. The device, furthermore, can be cheaply manufactured and may be conveniently applied to an ordinary lamp without in any manner altering the structure thereof. Moreover, it will be clear that when the chimney is removed the deflector-cone is removed with it, being entirely separate from and independent of the ordinary burner and its cone.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

' a cone-body of transparent material, divergentlydisposed arms projecting from the body and arranged to yieldingly engage the inner side of a lamp-chimney to frictionally hold the cone-body against movement therein, and means for securing the arms to the cone-body.

4. A deflector-cone for lamps, comprising a cone-body of transparent material, divergently-disposed arms depending from the lower portion of the cone-body and arranged to yieldingly engage the inner side of a lampchimney to hold the cone-body therein, and a ring secured to the cone-body and holding the arms thereon.

5. A deflector-cone for lamps, comprising a cone-body of transparent material having a flame-opening in its upper portion and a plurality of seats in its lower margin, of a holding-ring surrounding the lower portion of the cone-body and covering the seats, and a plurality of yielding arms having portions lo cated in the seats and held therein by the ring.

6. In a lamp, the combination with a burner-cone having a flame-opening, of a chimney covering the cone, a substantially transparent deflectorcone located wholly within the lower portion of the chimney over the burner-cone and in spaced relation thereto, said deflector-cone having a flame-opening registering with the flame-opening of the burner-cone, and means for detachably securing the deflector-cone within and on the chimney.

7. In a lamp, the combination with a burner-cone, of a chimney covering the cone, a substantially transparent deflector-cone located over the burner-cone, yielding arms depending from the deflector-cone and frictionally engaging the inner side of the chimney to hold said deflector-cone over the burner-cone, and a ring seduring the arms to the deflector.

8. In a lamp, the combination with a burner having upstandin chimney-retaining fingers and a cone locatedaetween thefingers, said cone havinga flame-opening, of a deflector-cone having a flame-opening, and resilient arms carried by the deflector-cone and arranged to detachably engage a chimney placed upon the burner, the flame-opening of the deflectorcone alining with the flameopening of the burner-cone when the arms are alined with the chimney-retaining fingers.

9. In a lamp, the combination with a chimney, of a substantiallytransparent de- Hector-cone located Wholly within the chimney over the burner-cone and in spaced relation thereto, and having outwardly-extending means that yieldingly engage the inner side of said chimney, said cone being frictionally supported by said means within and carried by the chimney.

10. In a lamp, the combination with a burner including the usual cone, of a chimney associated with the burner, and a substantially transparent deflector-cone having yielding means that engage the inner side of the chimney to thereby support the cone within the chimney during its application to and its removal from the burner, said deflector-cone being located'over the burner-cone when the chimney is in place on the burner.

11. In a' lamp, the combination with a burner including a cone, of a glass cone arranged above the burner-cone and adjustable toward and from the same.

12. In a lamp, the combination with a burner including a cone, of a chimney located on the burner and covering the cone, and a glass cone arranged within the chimney over the burner-cone, said glass cone having arms that engage the interior of the chimney and .adjustably hold said glass cone therein.

In testimony that I claim the foregoing as my own I have hereto aihxed my signature in the presence of two witnesses.
